Hi Lizette, IBM DASD DS8xxx. Some years ago there was RMF MAGIC, I don't know if is wtill used. For historical data, SMF is the only source. Maybe there are people that use TDS for example, and perform some queries. I'm just searching for the way you use when you are asked to perform a similar task.
